We have a Vutek QS3220 and we are printing color + white ink on a 60” clear PET window film.
We previously ran these with no problem, but all of sudden are encountering what looks like a "suction / print line" about every 10”. Since then, we have printed on canvas, regular adhesive back vinyl, and even 3/16" clear acrylic - all prints came out fine so we believe the issue lies with the suction since the PET film is so thin.
We have tried the following,
Any tips or advise would be appreciated.

We have tried the following,
- Printing on both left and right side of the flatbed
- Reducing the heat / vacuum levels
- Hooking the film onto both tension rolls (Previously when the prints came out correct, we had 100% suction and they were not hooked on the tension lines, it was fed by a table roller)
Any tips or advise would be appreciated.
